All users of the Village of Clyde POTW will
comply with all standards and requirements of the Act and standards
and requirements promulgated pursuant to the Act.
No user shall contribute or cause to be contributed,
in any manner or fashion, directly or indirectly, any pollutant or
wastewater which will interfere with the operation or performance
of the POTW. These general prohibitions apply to all such users of
a POTW whether or not the user is subject to National Categorical
Pretreatment Standards, or any other national, state, or local pretreatment
standards or requirements. Without limiting the generality of the
foregoing, a user may not contribute the following substances to the
POTW:
A.
Any solids, liquids, or gases which, by reason of
their nature or quantity, are or may be sufficient, either alone or
by interaction with other substances, to cause a fire or an explosion
or be injurious in any way to the POTW, or to the operation of the
POTW. At no time shall two successive readings on a flame-type explosion
hazard meter, at the point of discharge into the system (or at any
other point in the system) be more than 25% nor any single reading
be more than 40% of the lower explosive limit (LEL) of the meter.
Unless explicitly allowable by a written permit, prohibited materials
include but are not limited to gasoline, kerosene, naphtha, benzene,
toluene, xylene, ethers, alcohols, carbides, hydrides, and sulfides,
and any other substance which the Village of Clyde, the state, or
the EPA has determined to be a fire hazard, or hazard to the POTW.
B.
Solid or viscous substances which may cause obstruction
to the flow in a sewer or otherwise interfere with the operation of
the wastewater treatment facilities. Unless explicitly allowable by
a written permit, such substances include but are not limited to grease,
garbage with particles greater than 1/2 inch in any dimension, animal
guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails,
whole blood, feathers, ashes, cinders, sand, spent lime, stone or
marble dust, metal, glass, straw, shavings, grass clippings, rags,
spent grains, spent hops, wastepaper, wood, plastics, gas, tar asphalt
residues, residues from refining or processing fuel or lubricating
oil, mud, or glass grinding or polishing wastes.
C.
Any wastewater having a pH less than 5.0 or greater
than 10.0, unless the POTW was specifically designed to manage such
wastewater, or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment, and/or POTW
personnel.
D.
Any wastewater containing toxic pollutants in sufficient
quantity, either singly or by interaction with other pollutants (including
heat), to injure or interfere with any wastewater treatment process,
constitute a hazard to humans or animals, create a toxic effect in
the receiving waters of the POTW, or to exceed the limitation set
forth in a categorical pretreatment standard. A toxic pollutant shall
include but not be limited to any pollutant identified pursuant to
Section 307(a) of the Act.
E.
Any noxious or malodorous solids, liquids, or gases,
which either singly or by interaction with other wastes, are sufficient
to create a public nuisance or a hazard to life or are sufficient
to prevent entry into the sewers for their maintenance or repair.
F.
Oils and grease. Any commercial, institutional, or
industrial wastes containing floatable fats, waxes, grease, or oils,
or which become floatable when the wastes cool to the temperature
prevailing in the wastewater at the POTW treatment plant, during the
winter season; also any commercial, institutional, or industrial wastes
containing more than 100 mg/l of emulsified oil or grease; also any
substances which will cause the sewage to become substantially more
viscous, at any seasonal sewage temperature in the POTW.
G.
Any substance which will cause interference or pass-through.
H.
Any wastewater with objectionable color which is not
removed in the treatment process, such as but not limited to dye wastes
and vegetable tanning solutions.
I.
Any solid, liquid, vapor, or gas having a temperature
higher than 65° C. (150° F.); however, such materials shall
not cause the POTW treatment plant influent temperature to be greater
than 40° C. (104° F.). The Supervisor reserves the right,
in certain instances, to prohibit wastes at temperatures lower than
65° C.
J.
Unusual flow rate or concentration of wastes, constituting
slugs, except by industrial wastewater permit.
K.
Any wastewater containing any radioactive wastes,
except as approved by the Supervisor and in compliance with applicable
state and federal regulations.
L.
Any wastewater which causes a hazard to human life
or which creates a public nuisance, either by itself or in combination,
in any way, with other wastes.
No person shall discharge, directly or indirectly,
into the POTW, wastewater containing any of the following substances
in concentrations exceeding those specified below on either a daily
or an instantaneous basis, except by permit or as provided for in
this section. Concentration limits are applicable to wastewater effluents
at point just prior to discharge into the POTW (end of pipe concentrations).

A.
Except for chromium (hex), all concentrations listed
for metallic substances shall be as "total metal," which shall be
defined as the value measured in a sample acidified to a pH value
of two or less, without prior filtration.
B.
The allowable maximum daily shall be as determined
on a composite sample taken from the user's daily discharge over a
typical operational and/or production day.
C.
The allowable
maximum instantaneous shall be as determined on a grab sample taken
from the user's discharge at any time during the daily operational
and or production period.
D.
Other substances which may be limited are: antibiotics;
chemical compounds which, upon acidification, alkalinization, oxidation
or reduction, in the discharge or after admixture with wastewater
and its components in the POTW produce toxic, flammable, or explosive
compounds; pesticides, including algicides, fungicides, herbicides,
insecticides, rodenticides; polyaromatic hydrocarbons; viable pathogenic
organisms from industrial processes or hospital procedures.

B.
To assure that none of the above-noted limitations
are violated, the Supervisor shall issue permits to significant industrial
users limiting the discharge of the substances noted above. Each permit
shall restrict the discharge from each significant industrial user
to a portion of the total allowable influent loading. In determining
what portion of the total of each substance that each significant
industrial user shall be allowed to discharge the superintendent shall
consider:
(1)
The
quantities of each substance that are uncontrollable because they
occur naturally in wastewater;
(2)
The
quantities of each substance that are anthropogenic but are nonetheless
uncontrollable;
(3)
Historical
discharge trends;
(4)
Past
pollution control efforts of each significant industrial user as compared
to other significant industrial dischargers of the same substance;
(5)
Potential
for growth in the POTW service area;
(6)
Potential
for more restrictive regulatory requirements to be placed on the POTW
discharge or sludge disposal or sludge reuse method; and
(7)
Treatability
of the substance.
C.
The Superintendent shall apply a minimum fifteen-percent
safety factor protective of the POTW.
A.
Limitations on wastewater strength or mass discharge
contained in this chapter may be supplemented with more stringent
limitations when, in the opinion of the Supervisor:
(1)
The limitations in this chapter are not sufficient
to protect the POTW;
(2)
The limitations in this chapter are not sufficient
to enable the POTW treatment plant to comply with applicable water
quality standards or the effluent limitations specified in the POTW's
SPDES permit;
(3)
The POTW sludge will be rendered unacceptable for
disposal or reuse as the Village of Clyde desires, as a result of
discharge of wastewaters at the above prescribed concentration limitations;
(4)
Municipal employees or the public will be endangered;
or
(5)
Air pollution and/or groundwater pollution will be
caused.
B.
The limitations on wastewater strength or mass discharge
shall be recalculated not less frequently than once every five years.
The results of these calculations shall be reported to the Village
of Clyde Board. This chapter shall then be amended appropriately.
Any issued industrial wastewater discharge permits, which have limitations,
based directly on any limitations which were changed, shall be revised
and amended, as appropriate.
Except where expressly authorized to do so by
an applicable pretreatment standard, no user shall ever increase the
use of process water or, in any other way, attempt to dilute a discharge
as a partial or complete substitute for adequate treatment to achieve
compliance with a pretreatment standard. Dilution flow shall be considered
to be inflow.
Grease, oil, and sand interceptors shall be
provided, when, in the opinion of the Supervisor, they are necessary
for the proper handling of wastewater containing excessive amounts
of grease, flammable substances, sand, or other harmful substances;
except that such interceptors shall not be required for private living
quarters or living units. All interceptors shall be of type and capacity
approved by the Supervisor and shall be so located to be easily accessible
for cleaning and inspection. Such interceptors shall be inspected,
cleaned, and repaired regularly, as needed, by the owner, at his expense.
